FRP digesters and biogas ledge is unsaturated polyester resin, gel coat resin, chopped strand mat, high quality materials such as glass fiber cloth with mold after molding compound produced by several processes.Pool of the body surface, gel coat resin used to ensure the quality and reliability of sealing, high strength, light weight, corrosion resistance, anti-aging, anti-leakage characteristics. Product cell body by the upper and lower half of the assembly molding, and respectively with a hole, into, a gate and the water pressure, the high mechanical strength and elongation, greatly exceeding the required hydraulic digesters,the strength requirements. I produced the digester size fiberglass 6-100m3, small footprint, laying convenient, quick construction, to meet the different regions and geographical requirement. In the course of the cell body without maintenance, it is convenient for the users, welcomed by the majority of farmers and friends.
